SIIDABLE WINDOW R THE LIKE Application led September 7, 192,9, SerialNo. 390,972, and` in Great Britain September-15, 1928.

This invention relates to Vslidable'windows or the like, particularl butnot exclusively for use on ships and has special reference to the typeof slidable window wherein a glass holder is adapted to be slidablymoved in a fixed frame by hand operated gearing and is provided withprojections or cams that enable it to be moved away from its seating inthe fixed frame so that it can then be slidably moved without frictionand its seating face which is usually provided with a rubber ring thatcan be pressed against the fixed frame to provide a water-tightjoint. A

The chief object of the present invention is to simplify theconstruction of the slidable window and to enable the glass to bereadily removed from the glass holder in the case of breakagef'orfinstance, and replaced Without completely dismantling the window. A

According to this invention the fixed frame is provided projections onthe slidable glass holder which at its inner part or face is providedwith means, for example, projections or cams such as those aforesaid, toenable the glass holder to be moved and held away from its seating whenit is slidably moved. The said projection or cams which engage withrecesses or 30 grooves on the inner face of fixed frame when the windowis closed, may be provided on a retaining ring, which in conjunctionwith a flange on the glass holder serves to retain the glass in theholder. When it is desired to open the window, for example by operatinggearing such as that aforesaid, the

glass holder, as. it tends to be drawn downA` wardly, is first movedaway from its seating by the projections or cams engaging with bevelledor curved ends of the said recesses or grooves and after the projectionsor cams have moved out ofthe recesses they bear against the inner facesof the fixed frame and thus maintain the glass holder with its.

rubber seating ring out of engagement with the seating in the fixed'fra-me, at the same time providing a metal to metal contact whichfacilitates the sliding movement of the glass-holder. The said retainingring maybe secured to the glass holder in a readily dewith side groovesto receive lateral tachable manner so that after removing the same, theglass can be quickly taken out of the glass holder.

In order that the said invention may be clearly understood and readilycarried into eect, the same will now be described more fully withreference to the accompanying drawings, in which Figure l is a frontview of one construction of the improved sliding window for use onships. j Y

A represents the main or fixed frame which may befof any usual orsuitable construction and which is provided with side' grooves A1 inthe. part that receives the glass holder. B represents the glass holderwhich is provided at its sides with projections B1 that are disposed inthe l"aforesaid side grooves A1 in the frame A. The glass plate B2 isretained in the glass holder against a flange B3 by means of a retainingring C whichis detachably secured fto the glass holder by anumber ofscrews C1 (see Figures l and 2) andwhich extends beyond the inner faceor sides of `the fixed rame as shown. VAround the outer surface of theglass holder a rubber seating rin `D is provided and this'V is. adaptedto ie. pressed against a seating face A2 on the fixed frame so as tomake a water-tight closure, by means of retaining screws E that aremounted in lugs Ellandare adapted to bear on the inner surface of theglass holder. f The construction is such that limited movement.V of

the glass holder B with its seating ring D towards andaway from theseating A2 on the frame A is permitted. The retaining ring C extendsoutwardly beyond the glass holder and the extending portions areprovided with a number of projections or cams F whichrfit in recesses'or grooves G in the sides of the fixed'frame when the glass holder is inthe. closed position, the projections or cams being such that they canbe moved out of the recesses or grooves G when the glass holder is movedaway from its seating A2 in the fixed frame. At the lower part of theframe A gearing is provided for slidably moving the glass holder, whichlatter is loosely connected by a pin and slot H to a nut or block Ithreaded on a main operating screw J that can be rotated by handoperated bevel gearing K. In order to enable the sliding window to beopened, the aforesaid retaining screws E are first manipulated torelease the pressure on the glass holder B and the rubber seating ringD. The main operating screw'J isthen rotated by the bevel gearing K soas to cause the nut or block I to be axially moved. Owing to theprojections or cams F on the retaining ring C of the glass holder,engaging with bevelled or rounded surfaces at the lower ends of theaforesaid recesses or grooves C they are positively moved out of therecesses so asv to travel on the inner faces of the sides of the fixedframe. This movement results in the rubber seating ring D being moveddefinitely out of Contact with the seating A2 on the fixedframe toeliminate friction so that the sliding movement of theglass holder canbe effected whilst it is maintained in this position by the projectionsor cams engaging with the inner faces of the fixed frame, and providinga metal to metal contact that facilitates the sliding movement. Theglass holder ma be secured in any desired open position lily means ofthe aforesaid retaining screws E bearing against the outer surface ofthe retaining ring so as to clamp the glass holder against the fixedframe. When it is desired to close the window the aforesaid gearing isoperated in the reverse direction in order to raise the glass holder,which on being fully raised can be pressed by the retaining screws E sothat its rubber seating ring bears against the seating A2 in the fixedframe, this being permitted by the projection of cams F fitting in therecesses or grooves G. In order to enable the glass to be taken out ofthe glass holder, it is merely necessaryl to remove or displace the lugsEl carrying the retaining screws E and to take off the retaining ringVafter unscrewing the screws C1 thus leaving the glass free to beremoved. A new glass plate can then be placed in the glass holder andheld ytherein by screwing the retaining frame into position, whereuponthe lugs E1 carrying the retaining screws E can be positioned forenabling the latter to bear on the glass holder as required.

What I claim and desire to secure by Let- 1 ters Patent of the UnitedStates is 1. A slidable window of the type referred to, comprising afixed frame having interior side grooves, a glass holder having lateralflanges fitted to slide in said grooves, means for slidably moving theholder in said grooves, and projectionson the holder cooperating withthe fixed frame while moving thereover, as the holderl slides in thegrooves, for positively moving the holder away from the fixed frame.

2. A slidable window of the type referred to, comprising a xed framehaving interior side grooves, a glass holder having lateral flangesfitting in said grooves, means for slidably moving the holder in thegrooves of the fixed frame, a retaining rim on the holder for holding aglass in position therein, said rim extending laterally beyond the sidesof the holder and having means projecting from one face and engaginginboard surfaces of the fixed frame while moving thereover during saidsliding movement, to positively move the holder from the fixed frame.

3. A slidable window of the type referred to, comprising a fixed framehaving interior .side grooves, a glass holder fitting in said grooves, arubber seating ring between the glass holder and said frame, means forslidably moving the holder in said grooves, and cam members on saidholder cooperating with recessed walls of the grooves of the fixed frameto force the holder away from the frame and relieve the pressure on therubber seating ring as said holder slides in the frame.
